Appendix A: Parameter Reference List
Siemens Building Technologies, Inc. 167
Settings: 755= Analog input 1 2224 =Fixed PI setpoint (see P2201 to
P2207)
2250 =Active PI setpoint (see P2240)
Index: P2254[0] : IN000 (AUTO) 1st. Command data set
(CDS)
P2254[1] : IN001 (HAND) 2nd. Command data set
(CDS)
P2261 PID setpoint filter time constant
Min: 0.00 Def: 0.00 Max: 60.00
Level 3
Note: 0=no smoothing
r2262 CO: Act. PID filtered setpoint
Min: - Def: - Max: -
Level 2
Details: Displays PID setpoint in [%] after smoothing.
Note: r2262=100% corresponds to 4000 hex.
P2264[2] CI: PID feedback
Min: 0:0 Def: 755:0 Max: 4000:0
Level 2
Settings: 755= Analog input 1 setpoint 2224 =Fixed PID setpoint 2250 =Output setpoint of PID-MOP
Index: P2264[0] : IN000 (AUTO) 1st. Command data set
(CDS)
P2264[1] : IN001 (HAND) 2nd. Command data set
(CDS)
Note: When analog input is selected, offset and gain can be implemented using parameters P0756 to P0760.
P2265 PID feedback filter timeconstant
Min: 0.00 Def: 0.00 Max: 60.00
Level 2
P2267 Max. value for PID feedback
Min: -200.00 Def: 100.00 Max: 200.00
Level 3
Note: P2267=100% corresponds to 4000 hex.
When PID is enabled (P2200=1) and the signal rises above this value, the inverter will trip with P0222.
P2268 Min. value for PID feedback
Min: -200.00 Def: 0.00 Max: 200.00
Level 3
Note: P2268=100% corresponds to 4000 hex.
When PID is enabled (P2200=1) and the signal rises above this value, the inverter will trip with P0221.
P2269 Gain applied to PID feedback
Min: 0.00 Def: 100.00 Max: 500.00
Level 3
Note: Allows you to scale the PID feedback as a percentage value [%].
A gain of 100.0% means that feedback signal has not changed from its default value.
